Bits PA[7:0] are associated respectively with addresses ADDR[15:8],
DATA[15:8] and DATA[7:0], in narrow mode. When this port is not
used for external addresses such as in single-chip mode, these pins
can be used as general-purpose I/O. DDRA determines the primary
direction of each pin. This register is not in the on-chip map in
expanded and peripheral modes. Read and write anytime.
This register determines the primary direction for each port A pin
when functioning as a general-purpose I/O port. DDRA is not in the
on-chip map in expanded and peripheral modes. Read and write
